-6

Which of the following lines contains a valid, though not necessarily accurate, comment? - int twoPi = 3.14159; /* holds the value of two times pi */ - int twoPi = 2*3.14159; /* holds the value of two times pi //* - int twoPi = 2*3.14159; / / *holds the value of 6 //* - double twoPi = 2*3.14159; /* // holds the value of two time pi */ [comment] //

int twoPi = 3.14159; /* holds the value of two times pi */

Which comment below is the most helpful? - int volume; // declare an int - int volume; // declare volume - int volume; // declare volume to be an int variable - int volume; // size of trunk in cubic feet
